HOSE-COUPLING.

SPECIFICATION forming part of Letters PatentNo. 732,209, dated June 30, 1903.

Application tiled April 13, 1903. Serial No. 152,415. (No model.)

T0 all whom it may concern:

Be it known that I, JOHN P. MUEHLEBAGH, a citizen of the United States, residing in Kansas Oity, in the county of Jackson and State of Missouri, have invented a certain nevir and useful Improvement in Hose-Couplings, of which the followingis a specilication,

reference being had therein to the accom-- panying drawings, forming a part thereof.

My invention relates to improvements in hose-couplings.

The object of my invention is to provide a hose-coupling in which the joint between the two members is tightly sealed.

My invention has for its .further object the providing of a hose-coupling in which the two members may be quickly and rmly locked together and as readily disconnected. My invention provides on each member a protecting casing or casingsin which the locking mechanism or mechanisms are shielded from injury.

Other novel features of construction are hereinafter fully described and claimed.

In the accompanying drawings,which illustrate my invention, Figure lis a longitudinal sectional view of two members locked together. Fig. 2 is a top view ofthe same with the top plate ot' the near casings removed and a portion of one of the transverse plates in one of the casings broken away. Fig. 3 is a side elevation View of what is shown in Figs. 1 and 2, the near side plates of the casngs being removed to disclose the interior of the casings. Fig. 4 is across-section taken on the dotted line d b of Fig. 1 looking in the direction indicated by the arrow. Fig. 5 is a similar view taken on the dotted line c d of Fig. 1. Fig. 6 is a side elevation view complete, showing the two members united. Fig. 7 is a top View of the same. Fig. 8 is a longitudinal sectional view of portions of the two members detached, the resilient thimble being shown in elevation in one of the members. Fig. 9 is a top view of a modification of my invention in which the guides comprise tongues on one member and grooves in the other member. In this view parts are removed and some parts broken away and others shown in horizontal section, the two Fig. 10 is members being shown detached.

an end elevation view of the member shown on the-left in Fig. 9.

Similar characters of reference indicate similar parts.

1 indicates the hose.

2 and 3 indicate the two members, each adapted to be secured to a section of hose at one end and the two members beingadapted to slip one over the other at their free ends. The member 2 is provided with a recess 4 at one end, to which is fitted the reduced end of the member 3. The member2 is provided with an inner annular flange 5, disposed at the inner end of the recess 4. In Vthe member 2 is mounted a tubular open-ended resilient thimble 6, provided at one end with two annular peripheral flanges 7 and 8, between which the inner flange 5 is tightly fitted, thus retaining the thimble 6 in place. 'Ihe outer end ofthe thimble is tapering or conoidal in form and is adapted to enter and snugly lit the flaring outer end of the member 3. The end of the member 3 presses the flange S tightly against the iiange 5 when the members are united, as shown in Fig. 1. The

joint between the members is thus tightly' sealed, the pressure of the water in the members 2 and 3 serving to further thoroughly seal the joint.

Disposed diametrically opposite on the member 2 are mounted two rectangular casings 9, the outer ends of which are open and are adapted to abut against and register with two similar casings 10, similarly mounted upon the member 3. Upon the upper inner side of each casing l0 is secured a plate 11,

-the outer end of which is adapted to enter and fit between the sidewalls of the opposite casing and serving as guides to properly locate the two members relative to each other when they are slipped together. In each casing 9 are provided two transverse plates 12 and 13. Between each of said pair of plates is pivoted by apio l4,extendingthrough the plates,a longitudinally-disposed laterallymovable lever 15, the outer end of which is hooked in form and adapted to engage an inwardly-extending hook or projection 16, mounted one on each plate 11. Between each pair of plates 12 and 13 and bearing upon the casing 9 and connected to the lever IOO is a Hat spring 17, the tension of which normally forces the hooked vend of the lever 15 to engage the adjacent projection 16. The other end of each lever 15 is provided with an operating-arm 18, which extends through slots 19, provided in the plate 12 and the top of each casing 9. The outer end of the'said arm 1S may be provided with a button 20', by which the lever may be swung.

In the form of myinvention shown in Figs. 9 and 10 the parts are constructed as above described, excepting that instead of the plates l1 being formed to serve as longitudinal guides for the members the reduced end of the member 3 is provided with diametrically oppositely disposed longitudinal tongues 21, adapted to enter and fit corresponding recesses 22, provided in the recessed end of the member 2.

In operating my invention, the parts having been constructed and assembed as described, it is but necessary to slip member 3 into the recessed end`of member 2, with the outwardly-extending ends of plates 1l inserted in the casings 9. By forcing the members together the levers l5 will be forced past the projections 16 against the pressure of springs 17 and will then engage the said projections, as shown in Fig. 2 in dott-ed lines. vWhen the levers are so engaged, the casings 9 and 1,0 will be forced against each other and the fiange 8 will be tightly compressed against the flange 5 of the member2 by the end of the member 3. To detach the members, it is but necessary to force the but'- tons 2O in adirection such that the hooked ends of levers 15 will be freed from the projections 16, at which time the members may be drawn lengthwise apart. The plates 11, entering the casings 9 in one form of my invention, and the tongues 21, entering therecesses 22 in the other form of my invention, prevent turning relatively of the members and relieve the levers 15 from any lateral strain. When united, the connecting parts of the members are fully covered and protected, and the hose may be used roughly and drawn .over obstructions without injury to any of the parts.

My invention may be variously modified without departing from its spirit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
